Deathrun edition! (because I haven't played ordinary TF2 since February)
* When the Activator doesn't advance through certain points of the map for the entire round just to be a dick, making it impossible for the red team to move on.
* When you have those last few runners that doesn't advance and just fap around until the round is over.
* "I'm not going to go, you go first!"
* "I died because of lag/my keyboard/my mouse/my shitty team/this shitty map !rtv"
* The dead-chat, so much complaining over everything and everyone!
TL;DR: Players, stop being dicks!
